What it can do
Written by Robotheca from the project's documents.
- Drives autonomously through the WRO Future Engineers Open Challenge and Obstacle Challenge without wall contact.
- Uses a reactive LIDAR controller reacting to four distance sectors (front, left, right, back) to steer and set speed.
- Detects green and red pillars with a front camera and passes them on the correct side.
- Performs a parallel-parking maneuver into an unknown bay in the Obstacle Challenge.
- Splits computing: Raspberry Pi 5 handles perception and navigation, Pico 2 drives motor and steering from received commands.
- Monitors battery state of charge and can shut down gracefully at a minimum battery level.

Wiring and electronics
Notes written by Robotheca from the project's documents.
Main parts
- Raspberry Pi 5 single-board computer for perception and navigation.
- Raspberry Pi Pico 2 microcontroller for motor, servo and telemetry control.
- RPLidar S3 360-degree LIDAR for distance sensing.
- Fish-eye camera with 640x480 at 30 fps capture for pillar detection.
- BNO085 IMU for orientation sensing.
- 20GP-180 DC gearmotor with quadrature encoder for driving the rear wheels.
- Motor driver circuit between the Pico 2 and the drive motor.
- Surpass Hobby S0009M digital servo for steering.
- UPS module reporting battery state over I2C, feeding a 5V logic rail, with motor power stepped up to 12V.
- Physical power switch on the battery/UPS pack.
Connections
- Raspberry Pi 5 is the I2C master and the Pico 2 is an I2C slave on the link between the two boards.
- The Pico 2 sends PWM and direction signals to the motor driver, which powers the 20GP-180 motor.
- Encoder signals from the 20GP-180 motor are wired back to the Pico 2 encoder inputs.
- The steering servo is driven by PWM directly from the Pico 2.
- The UPS module reports battery state over I2C on register 0x17.
- The 5V logic rail powers the Raspberry Pi 5, Pico 2, camera, IMU and LIDAR; motor power is stepped up to 12V separately.
